Best for SP+

A fair comparison starts by acknowledging where the other vendor is the right call. SP+ is a real product with a real fit. These are the buyer profiles who should probably stick with SP+ (or pick it new), not replace it with Park Graph.

  • Owners who want a large operator

    SP+ is part of Metropolis, which says it runs the largest parking network in North America, with more than 4,000 locations.

  • Facilities that need staff on site

    SP+ offers parking management, self-parking operations and valet, per its own site.

  • Gated garages

    At gated facilities, SP+ uses digital platforms, license plate recognition and custom integrations.

Best for Park Graph

And these are the buyer profiles where Park Graph is the better fit — the cases where the operating shape, the cost model, or the AI-agent surface tilt the comparison toward operator-side software.

  • Owners who want to keep control

    You set the rates, the hours and the rules. You see every session and payment in your dashboard.

  • Owners of one lot or a few

    Starter covers up to 3 lots at $0 a month. You do not need a portfolio to get a good tool.

  • Owners who want to start today

    Sign up, add your lot and set your rates. Print the QR sign on any printer and post it. There is no hardware and no install visit. A lot can be live the same day.

  • Owners who want $0 a month

    Starter has no monthly fee, no setup fee and no contract. You pay 10% per payment (minimum $0.75), and less on Pro (5%) or Enterprise (3.3%).

  • Drivers who do not want another app

    They scan the sign, pay in the browser with Apple Pay, Google Pay or a card, and go. Scan to paid takes under 30 seconds.

  • Owners who want AI assistants to find their lot

    Every plan makes your lot findable through the public API and MCP server. On Pro and Enterprise, Claude and ChatGPT can book and pay for a space.

  • Owners who price for busy nights

    Event pricing and surge pricing come with Pro and Enterprise. The price a driver is quoted is the price they pay.

Feature matrix

A row-by-row look at how the two products handle the things operators actually have to deliver — the driver flow, the operator dashboard, the API surface, the brand on the receipt. Where SP+'s row reads “not publicly documented” or “partner-only,” we checked their public site on the date noted in the Sources section.

Pricing model — qualitative comparison

SP+ is an operator, so its fees sit in each management agreement. They are not in the sources we checked.

Park Graph publishes every price. Starter is $0 a month and 10% per payment, with a $0.75 minimum. Pro is $499/mo and 5%. Enterprise is $4,950/mo and 3.3%. Stripe's card processing fee applies on top. Starter has no setup fee, no hardware and no contract.

One lot or many, every Park Graph fee is the published number.

SP+'s fees to property owners are not in the sources we checked, so this page quotes none. Park Graph's pricing is published at /pricing.

Deployment, hardware, and time to launch

SP+ fits each facility to its needs. At gated sites it uses digital platforms, license plate recognition and custom integrations. At non-gated sites it creates a controlled, free-flow environment.

Park Graph takes the shortest path. Sign up, add your lot and set your rates. Print the QR sign on any printer and post it. There is no hardware and no install visit. A lot can be live the same day.

The single biggest practical difference between Park Graph and SP+ on most lots is how long it takes to accept the first paid session. Print, post, and accept payments — same day — is a different shape of operating motion than a procurement, install, or marketplace listing review.

AI-agent readiness, public API, and MCP

We found no public MCP server or self-serve developer API for SP+ or Metropolis on Nov 14, 2026.

Park Graph runs a public MCP server and ChatGPT Actions. On every plan, assistants such as Claude and ChatGPT can find your lot through the public API. On Pro and Enterprise, they can also book and pay for a space at the rate you set. API keys and webhooks come with Pro and Enterprise, so your own systems see each booking.

AI-agent commerce moved from theory to a real distribution channel in 2025 and 2026. Drivers ask ChatGPT, Claude, Gemini, and Perplexity to find and pay for parking at the destination they are headed to, and assistants that speak Model Context Protocol can complete that transaction inside the chat. Park Graph publishes a public MCP server and ChatGPT Actions manifest so any lot in the network is reachable to those assistants. See our MCP server and ChatGPT Actions docs for the full surface.

QR-payment comparison

With Park Graph, the QR sign is the whole driver flow. Drivers scan the sign at your lot. They pick a time and pay in the browser with Apple Pay, Google Pay or a card. No app and no account. Scan to paid takes under 30 seconds, and the receipt names your lot.

SP+ uses digital payment platforms that vary by facility, per its own site. The sources we checked do not name one default driver flow.

A working QR-pay flow is now table stakes for any operator who wants to capture walk-up demand. The right comparison question is not “does the vendor support QR” (most do at this point) — it is “is QR the default driver flow with no app install required, or is it an add-on to the primary flow?” That distinction shows up directly in driver conversion at the lot.

Park Graph QR-payment flow versus SP+: a driver scans a printed lot code, picks a duration, pays with Apple Pay or card, and receives a digital pass in under thirty seconds with no app install
Scan-to-paid in under thirty seconds, no app install — the default driver flow, not an add-on.

Migration path

If SP+ manages your facility, start with your agreement and its notice terms.

Then try Park Graph on one lot first. Step 1: sign up for Starter. Step 2: add the lot and set your rates. Step 3: print and post the QR sign. Step 4: compare revenue per lot after thirty days.

Most operators run both products side by side for thirty days before making a per-lot decision. The cost of running both is small (a printed sign and a free Starter plan on the Park Graph side); the cost of switching prematurely on a single hunch is much larger. We are happy to help design that thirty-day comparison — see our contact page.

Park Graph is AI-native parking management software.
